High resolution 3D terrain mapping with low altitude imagery
نویسندگان
چکیده
This paper presents an approach to build a very high resolution digitial terrain model with the imagery provided by a stereovision bench mounted on-board a balloon flying at low altitude. The approach is a “simultaneous localization and mapping” procedure, that enables to build a spatially consistent map, by allowing to recover the balloon position with a very high accuracy: only imagery is used for that purpose, and no position sensor is required. Results show the possibility to build a 5cm resolution digital elevation map of several thousands square meters areas from images acquired below 100m altitude.

High resolution terrain mapping using low altitude aerial stereo imagery
This paper presents an approach to build high resolution digital elevation maps from a sequence of unregistered low altitude stereovision image pairs. The approach first uses a visual motion estimation algorithm that determines the 3D motions of the cameras between consecutive acquisitions, on the basis of visually detected and matched environment features. An extended Kalman filter then estima...
